[mapserver-users] Color palette for road-like layers

[thomas bonfort]

there are also some planned features to simplify that syntax. (this is
how the mapfile to generate the map on the mapserver fron page is
written).

mapserver code:
http://svn.osgeo.org/mapserver/sandbox/graphics  (sticking with
revision 8254 unless you want to feel daring)

mapfile excerpt:
http://code.google.com/p/mapserver-utils/source/browse/trunk/highways.map#862

regards,
thomas
